Plain-English summary
AB Sciex, LLC is recalling 38 units of the 4500MD Triple Quad Mass Spectrometer (Part Number 5032522) distributed nationwide in the United States.
In rare circumstances, a leak of highly flammable solvent at the ion source probe combined with an electrical discharge may ignite a flame on top of the probe. This could result in the ejection of the electrode assembly. The flame poses a risk to operators, patients, customer property, and the environment if left unattended.
Additionally, the failure may delay patient test results. This recall was initiated due to the potential for health risk and property damage.
